In an effort to control algae growth, catfish farmers in the Southern United States introduced Asian Carp -- a species of fish found in China -- into their ponds in the 1970s. Flooding throughout the last several decades washed the fish out of those ponds into other waterways. Gradually, the species multiplied and spread north along major rivers such as the Mississippi and the Illinois. Now, as Asian Carp outnumber native fish in many areas, their expansion threatens the fragile ecosystems of the Great Lakes. VOA's Kane Farabaugh has more on the fight to control and contain the invasive Asian Carp.
